Hiroshima - august 6 1945
Nagasaki - august 9 1945
For six months, the United States had made use of intense strategic fire-bombing of 67 Japanese cities. Together with the United Kingdom, and the Republic of China the United States called for a surrender of Japan in the Potsdam Declaration. The Japanese government ignored this ultimatum. By executive order of President Harry S. Truman, the U.S. dropped the nuclear weapon "Little Boy" on the city of Hiroshima on Monday, August 6, 1945,[1][2] followed by the detonation of "Fat Man" over Nagasaki on August 9. These two events are the only active deployments of nuclear weapons in war.[3] The target of Hiroshima was a city of considerable military importance, containing Japan's Second Army Headquarters, as well as being a communications center and storage depot.[4]

During the final stages of World War II in 1945, the United States conducted two atomic bombings against the cities of Hiroshima and Nagasaki in Japan.
The first bomb was dropped on Hiroshima on August 6, 1945
The second bomb was dropped on Nagasaki on August 9, 1945

On the morning of Monday, August 6th, 1945, (at about 8:15 a.m. local time) the United States Army Air Forces dropped the nuclear bomb "Little Boy" on Hiroshima, followed three days later (Thursday, August 9th at about 11:01 a.m. local time) by the "Fat Man" bomb dropped on Nagasaki.

Within the first two to four months of the bombings, the acute effects killed 90,000-166,000 people in Hiroshima and 60,000-80,000 in Nagasaki,[5] with roughly half of the deaths in each city occurring on the first day. The Hiroshima prefectural health department estimates that, of the people who died on the day of the explosion, 60% died from flash or flame burns, 30% from falling debris and 10% from other causes. During the following months, large numbers died from the effect of burns, radiation sickness, and other injuries, compounded by illness. In a US estimate of the total immediate and short term cause of death, 15-20% died from radiation sickness, 20-30% from flash burns, and 50-60% from other injuries, compounded by illness.[6] In both cities, most of the dead were civilians.[7][8][9]
